CORNER-FINISI-IER FOR IRRIGATION.

Application filed October 29, 1917.

To all whom it may concern:

Be it known that I, JAMES M. Coox, a citizen of the United States, residing at Anaheim, in the county of Orange and State of California, have invented new and useful Improvements in Corner-Finishers for Irrigation, of which the following is a specification.

My object is to make a dirt scraper for use in irrigating work, and my invention consists in the novel features herein shown,

' described and claimed.

Fig. 4 is a diagram illustrating the op-.

eration of the machine.

Fig. 5 is a fragmentary vertical sectional detail on the line 55 of Fig. 1.

The scraper blades 10 and 11 are runnershaped, mounted vertically with their rear ends spaced apart to form the throat 12 which is the width of the desired ridge to be made, and their forward ends spaced wider apart to the extent of the widths of the desired ditches to be made, and the scraper blades are rigidly connected together in this position by cross braces 13, and a d aft rigging, comprising the tongue 14 and suitable hounds, is connected to the braces 13. The scraper is intended to be drawn by a pair of animals hitched to the tongue 14: and when drawn over loose ground each blade 10 and 11 will gather the dirt between their forward ends and move it inwardly, thus making two ditches and a ridge,

The dumping scrapers 15 and 16 which serve as corner finishers are mounted on opposite sides of the rear ends of the blades 10 and 11. Each dumping scraper com- )rises a two-endcd scraper plate 17 rigidly hxed upon an axle 17 said axle extending horizontally across the center oi? the plate, and trunnions 18 and 19 extend from the ends of the axle. Supporting arms 20 and 21 extend downwardly from the adjustable frame bar 20, and the trunnions 18 and 19 are rotatably mounted through the lower ends of these supporting arms 20 and 21. Draw bars 21 extend forwardly from the ends of the frame bar 20 and the upper Specification of Letters Patent.

ends of the supporting arms 20 and 21, and braces 22 extend from the lower ends of the supporting arms 20 and 21 to the forward ends of the draw bars 21'. The forward ends of the draw bars 21 are bent downwardly at right angles to form the adjusting bars 23, said adjusting bars being mounted in U-clamps 23 inserted through the cross bar 22 and held by set-screws 24:, so that by loosening the set screws the adjusting bars 23 may be raised or lowered, the set screws tightened, and the bars held rigidly in their adjusted positions. The cross bar 22 is rigidly mounted u on one of the braces 13 and extcn s both ways beyond the scraper blades 10 and 11 so that the plates 17 are substantially in the centers of the ditches formed by the scraper blades 10 and 11. The plates 17 are reinforced along their scraping ends by cutting blades 25 and 26, and side wings 27 and 28 extend forwardly from the ends of the cutting blades 25 and 26 and the side edges of the plates 17 so as to make a housing which will hold a considerable quantity of dirt. The cutting blades 25 and 26 and the wings 27 and 28 are oppositely disposed, as shown in Fig. 2, and extend forwardly at the lower ends of the blades and backwardly at the upper ends. Of course, when the plates are reversed, the same relative arrangement prevails.

Trip levers 29 are pivotally mounted in bearings 29 fixed to and extending forwardly from the frame bars 20', said levers being substantially vertical, and rollers 30 are mounted at the lower ends of the levers, said rollers being in position to bear against the forward faces of the upper edges of the plates 17 and hold, the plates against rotation upon the trunnions 18 and 19, and retractile coil springs3l connect the upper ends of the levers 29 to the frame bars 20, the tension of the springs being exerted to hold the rollers 30 in their downward positions. Foot-levers 32 and 33 are mounted upon cranks 32 and 33' fixed upon rock-shafts 32 and 33 mounted in transverse alinement in bearings fixed to one of the braces 13, and cranks 32 and 33 are fixed to the outer ends of the rock-shafts 32 and 33, and chains 32 and 33 connect the outer ends of the cranks 32 and 33 to the upper ends of the levers 29, so that when a foot-lever 32 or 33 is pushed forwardly and downwardly by the operator occupying the seat -A, the corresponding lever 29 is operated to raise the roller 30 out of engagement with the end oi? the and allow the plate to rotate hy contact with the ground.

Tire bands 34 and 35 each form substanielly a hal c r le with t ei d vturned inwardly, and these in-t irned ends are rigidly fixed to the endsof the plates 17 Q as t mak e ment 9f h nd Wh beh m h s epi' ieu m l ha s, hots ne' he th r, s th Whee he ousn 'i mconme h th a e d i s-C with dirt to th desired extent hr the dirt r ed" o th d ired Po n t were $'6pmt i" 9 elee e roller 50 m ts efil positipn nd he i w n" the e i iii s d mpa t by h awa mo emen 'bf the h ne nd the co'ntact"heeen "th h ueme and he Emma" "Then the" bands er or 35 will gontacf with the gleli ndir ta e he dumping a p re a f e bli qn t B ng th rh u n 'iiit 'd operation.
